ROTARY ENGINE.

Specification of Letters Patent.

Application filed November' 9, 1909. -Serial No. 527,014.

4in a pair of pistons are geared together by means of the blades or vanes intermeshing, wherein the motive fluid. is directed squarely against the operative face of the blades or vanes, and wherein the motive Huid will act on the blades or vanes with equal facility in either direction.

Referring to thedrawings forming a part hereof-Figure 1 is a longitudinal section of the improvement. Fig. 2 is a section on the line 2-2 of Fig. l. and Fig. 3 is a section on the line 3 3 of the same figure.

The embodiment of the invention shown in the drawings comprises a casing, composed of a base 1, an elliptical ring 2, and cover plates 3, which are secured to the ring by cap screws 4, passing through openings i'n the cover plates and engaging threaded openings in the ring.

Each of the cover plates is provided with spaced bearings 5, and shafts 7 and 8 are journaled transversely of the casing in .the corresponding bearings. A rotor comprising a disk 9 provided with gear teeth- 10 is secured to each shaft, and the disks are of such size that the teeth 10 of the two disks interinesh, at the longitudinal center of the casmg. a

The end walls of the casing are concentric with the adjacent shaft 7 or 8, and the teeth l0 do not. contact with the said end walls, nor with the inner surface of the casing. A packing plate 11 is arranged within a depression 12in each end wall, the said plates extendingentirely across the space b'etween the cover-plates.

Each "plate is of considerable width as "shown, and is provided with a plurality of `openings 18, through .which the-motive fluid may passinto the recess 12, to hold the plate outwardly, so that the teeth will vcontact therewith .during the rotation'ofthe, disk.'

It will be observed that vthe packing plates Patented 1910,

1l are arranged at the exact vertical center of the interior of the casing, so that the i motive fluid acts over an equal distance."

whether entering through the port llt at the top of the casing, or through the port 15 at',r I.

the bottom thereof.

Each 0f the disks is provided in. b'Othl l faces with an annular groove 16, concentric with the shaft, and a packing ring 17 is'seatf v ed in each groove, the ring being supportedf' depressions 19 m,"i

bysprings 18 seated in the bottoms of the grooves. l

Each of the annular grooves is Aprovided `at spaced intervals with radial extensionsV 20. which extend along the ends of sundry of the teeth, almost to the tips thereof, and

the packing rings 17. are provided with radialextensions 21 fitting therein, and supported by springs 2Q- seated in depressions 23 in the disks. The rings 17 and the exten-A "u sions 21, move in contact'with the cover' plates, and make a steam tight jointb,e` i

tween the disk and the s'ai'd plates, while the packing plates l1 make a steam-tight jointl at the vends of the casing, between thesaid ends4 and the disks. v

Intermediate the disks, .the upper and lower walls of the casing are provided with projections 24 and Q5 respectively, which extend 'toward each other, and are concaved on each side as at 26, to conform to the curvature of the disks. Each of the said projections is provided with a transverse passage 27, with which the inlet 1st or the outlet -15 communicates. through the projections 24 and 25 is exactly horizontall as indicated in 'Fig'. 1, lso that the motive -tluid is directed horizontally against'the teeth 10, which are the blades or vanes of the rotor. The disks are keyedto the shafts 7 .and 8 by means of keys 28, power may be taken from either Shaft. l i

In operation, `the motive fluid is admitted .through the port 14, which is the inlet port` As it reaches the passage 27 it is directed to lthe right and left, and impinges against-the The passage 27A ilo the rotors are moving the motive fluid acts on the Varies the greatest possible length of time.

I claim: n

1. A rotary engine comprising a pair oi' parallel shafts, a disk on each shaft, a plurality of blades or Vanes on the periphery et" each disk and parallel With the shaft, a Casing inclosing the disk and in which the shafts are journaled, the blades on one disk meshing With the blades on the other disk, the free edges of the blades on both disks moving out of contat-.t with the easing Wall, a packing plate at `eaeh end el the easingf and against which the. tri edges of the blades inove, said plates beine' iii the saine horizontal line with the sbalts, said Casing; having an inlet, at its top between the shafts and an outlet in its bottoni between the.

shafts.

2. A rotary engine comprising' a easing a pair of shafts joiii'naleil therein, in spaced parallell relation, disks on the shafts, bladesl or vanes on the disks, the blades oi. one disk meshing with the blades of the other disk, i a easing iiielosiiig the disks, a. packing' plate at each end of the easing toi' engagement by the free edges of the blades said plates being in the plane of lthe shafts for. the purpose speeified,'and said easing having at its top an inlet port and at its bottom an outlet port, said ports being between the shafts,-

said easing; having a projection from its top and bottoni Wall between the shafts' and provided with a horizontal transverse passage opening' toward both disks and With which the adjacent. porteeiniiini'iiezites.

3. A rotary engine eoinp'i'ising a easing, a paii.` or' shafts joiii'iialed therein in spaced parallel relation, disks on the shafts, blades oi' Yanes on the disks, the blades of .one disk vmeshing with the blades of the other disk, a
